Title: Control device and control method of stepping motor
Inventor: SHIMADA Ayaka
IPC: H02P8/32
Filed: 2018-06-20
Abstract: To provide a control device of a stepping motor enabling a hold control which can reduce excitation current smoothly at a rotation stop of the stepping motor.SOLUTION: A control device 10 of a stepping motor 20 rotates a rotor by flowing excitation current through a plurality of coils. The control device 10 has: a driving circuit 40 applying driving voltage to the coils and; a control circuit 30 controlling the driving voltage. The control circuit 30 performs a hold control of shifting the rotor to a predetermined stop position by changing amplitude of the excitation current flowing through the coils so as to become close to a target current value which gradually decreases within a hold period when the stepping motor 20 stops rotating. The control circuit 30 sets an operation mode of the driving circuit 40 to an operation mode corresponding to a comparison result between the amplitude of the excitation current and the target current value among a plurality of operation modes, per predetermined cycle in the hold period. The plurality of operation modes include a charge mode increasing the excitation current and a first attenuation mode attenuating the excitation current.SELECTED DRAWING: Figure 1
